ALARM-CLOCK ATTACHMENT.

Specification of Letterslatent.

Patented Feb. 10, 1914.

Application filed February 1, 1913. Serial N01 745,608.

To all whom it may concern Be it known that I, RAYMOND P. PACKARD, a citizen of the United States, and a resident of Tacoma, in the county of Pierce and State of Vvashington, have invented a new and Improved Alarm-Clock Attachment, of which the following is a full, clear, and exact description.

My invent-ion relates to a device intended to be used in connection with ordinary alarm clocks, and the object thereof is to cause alamp to be lighted when the alarm is rung. M

The attachment comprises connections which are controlled by the position of the parts of the alarm mechanism and are so arranged further that the lamp can be caused to remain lighted so that the same can be kept in use after the alarm has ceased.

Reference is to be had to the accompanying drawings forming a part of this specification, in which the same characters of refer ence indicate the same parts in all the views.

Figure 1 is a front elevation of my attachment, showing the alarm clock in operative relation; Fig. 2 is a top plan of the attachment with the clock remoged; and Fig. 3 is a diagram showing thearrangement of the controlling connections.

The attachment comprises a holder for the clock,including a base 1, side Walls 2 and back 3, the top and front being open, and the front being provided with retaining strips 4 attached to the adjacent edges of the sides to keep the clock in place and at the same time allow the face to be exposed. The clock is put in position by lowering it through the open top of the holder, as will be readily understood.

On tho'inner faces ofthe sides of the holder are electric contacts 5 in the form of metal springs, and these springs are connected by means of conductors to a suitable source of electric current. are arranged to press against insulated contacts 6 carried upon the framework of the clock. These contacts 5 and 6 form part of an electric circuit which is controlled by alarm-sounding mechanism which will now be described.

I intend to use my attachment with alarm clocks of ordinary construction, and such clocks generally have a springishownat 8 which controls the mechanism which rings the 11 to sound the alarm, and for this purpose ,it is controlled by a. catch 9, so that the These contacts spring can be released and the alarm sounded when the desired moment arrives. This spring 8 carries a metallic projection 10 which cooperates with a pair of spring contacts 11. These spring contacts, as Well as the contact 10, will be insulated from the frame 7, and one of the contacts 11 will be connected by means of a conductor 12 to one of the contacts 6, say the contact at the loft and the terminal of the lamp 13 connected to one of the contacts 11 is joined by a similar conductor 15 to the otluer terminal of this switch.

The manner in which my attachment 0 crates will now be set forth. If the alarm is Wound up, then at the desired moment when the catch 9 releases the spring 8, the alarm will be sounded and the contact end will bridge the space between the contacts 11 to close the circuit through the lamp 13. The contacts 5 and 6, the contacts 11 and the lam 13 all may be in series with a convenient source of current shown atl, and if desired I may join these parts by means of a series connection to the wiring which energizes the lights of the house or other building in which the attachment is to be used.

Therefore, as soon as the alarm is sounded the lamp 13 lights up and the person who is to be aroused by the alarm finds the room lighted when he awakes. After the alarm is finished sounding the light 13 will remain lighted, and if at any time it besdcsired to use the lamp. 13 without reference to the a switch 16,.

alarm clock, the switch 16 is moved to closed position.

It will be seen that I can also cause the lamp 13 to be energized by means of my invention whether the alarm bell rings or not. For instance, if the alarm. incaianism is not wound up the alarni will not sound when the catch 9 releases the spring 8, but the release of the spring in this instance will cause the circuitto be closed, the same as in the former instance. This is a feature of value, as in many places, such as hospitals, it may be desired to wake the nurse at a certain hour without arousin lamp be located in such a place as to throw the patients, and it tho 16 may be located at the head of the bed in a room so as to enable the occupant to ob tain light from the lamp 13 whenever he wants to use this lamp. Furthermore, if for any reason the person awalres before the alarm goes off he is sure that he has awakened too early, because he will find no light in the room. Furthermore, when the alarm does go off a sudden bright light in the room will serve as an additional reminder for the sleeper to rise,

I wish to have it understood that the above description is illustrative only and that I do not care to be limited to the exact details shown and described, but wish to re serve to myself the right to make' such changes in the shape, size and arrangement of the parts as fairly fall within the scope and spirit of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In an alarm clock attachment, the comhination of a. holder, a contact on the inner face of the holder, a source of electrical energy with which the contact of the holder is connected, an alarm clock in the holder and having a contact on its alarm releasing means, a contact on the outer face of the clock casing and engaging the contact of the holder, a pair of contacts on the clock and with which the contact of the alarm releasing means is'adaptcd to engage, one of the said pairs of contacts having one of its contacts connected withthe contact carried by the clock and engaging the contact of the holder, and a lamp having one terminal connected with the other contact of the said pair of contacts and its other terminal conncc'ted'with the source of energ 2. The combination of an alarm clock, a holder in which the clock fits, a pair of con tacts on the inner face of said holder, at source of energy connected thereto, a pair of contacts on the outer face of the clock casing in position to cooperate with the cont: ts carried bythc holdcr,a conductor connected to each of said contacts carried by the clock, an electric lamp connected with the said conductors, releasable means carried by the clock for allowing the same to sound an alarm, and means carried by said releasable means for bridging said conductors to complete the circuit through said lamp when the time for sounding the alarm arrives, whereby the lamp will then be energized.

3. The combination of a holder having an open front and top, contacts on the inner faces of the sides of the holder, an alarm clock in the holder, contacts on-the outer ace of the clock casing and engaging the contacts of the holder, a source of current connected to the contacts on the holder, :1 pair of contacts on the clock, a conductor connecting one of the contacts of the pair of contacts with one of the contacts on the clock casing, an electric lamp, a conductor connecting the lamp with the other contact on the clock casing, a conductor connecting the lamp with the other contact of the pair of contacts, and a releasable spring carried by the clock for allowing the same to sound an alarm, said spring carrying a contact adapted to bridge the said. pair of contacts.-

4-. The combination of an alarm clock having contacts on the outer face of its casing, a holder in which the clock fits, said holder having contacts on its inner opposing sldes,

and with which the contacts of the clock casing engage, a source of current connected to the contacts of the holder, a pair of contacts carried by the clock, a conductor connecting one of the said contacts with one of the contacts on the clock casing, an electric lamp, a conductor connecting the lamp with the other contact of the pair of contacts, a conductor connecting the lamp with the other contact on the clock casing, a releasable spring carried by the clock for allowing the same to sound an alarm, sa d spring carrying a contact bridging the pair of contacts, a switch, a conductor connecting one of the contacts of the holder with one terminal of the switch, and a conductor connecting the other terminal of the switch with one terminal of the lamp.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
